2 Claims. 1

The present invention relates generally to improvements in the art ofventilation, and relates more particularly to improvements in theconstruction and operation of storm sash ventilators.

It has heretofore been common practice to provide ventilators associatedwith storm sash of buildings for permitting a moderate supply of freshair to the building interior without necessity of opening the stormwindows; to which the ventilators were applied. These prior storm sashVentilators usually consisted of one or more holes bored or otherwiseformed through the lower rail of each sash, and a closure plate of wood,metal, or the like for the hole or holes attached to theinner side oftherail in a manner such as to permit movement to various positions forcovering or uncovering the holes to varied extents. In such prior artventilators, however, it was always deemed advantageous to form theadjustable closure plate in a manner such as to provide the tightest andclosest possible fit, particularly when in closed position; and onecommercially successful type of storm sash ventilator in prior use isshown and described in Patent No. 2,101,941, dated December 14, 1937, toWilliam C. Hansen andHenry J. Goelzer. However, these priorclose-fitting ventilating devices have proven somewhat objectionable inthat circulation of air adjacent the glass pane was eliminated andhumidity within the room was usually lowered when the tight-fittingclosure plate was in closed position, thereby resulting in formation ofcondensation and front on the pane; and furthermore since the customaryclosure plates were movable upwardly to open the vent holes, the aircirculated by these openings could notbe properly directed and uniformlydistributed to effectively prevent formation of condensation or frostwithout opening the closure plates to the fullest, extent.

It is therefore a primary object of my present invention to provide animproved storm sash ventilating assemblage which is simple inconstruction, and eihcient in operation, and which obviates theobjectionable features and disadvantages of the prior ventilators.

A more specific object of my invention is to provide an improved stormsash ventilating assemblage wherein a limited amount of air isconstantly directed and circulated, as in spaced jets, uniformly acrossthe inner surface of the stormwindow pane, thereby tending to equalizethe temperature on both innerand outer surfaces of the pane andminimizing. the possibility of condensation and frost formation.

- 2 Another specific objectof this inventionis. to provide an improvedstorm sash ventilator which may be readily. manufactured of sheet metalor the like with the aid. of punches and dies, and which may also bereadily applied and utilized:

by a novice without need of special equipment.

An additional specific object of the invention is to provide an improvedstorm sash ventilating assemblage-of the type having-one or moreslots oropenings adapted to be covered by an adjustable plate, the plate beingprovided witha series of spaced channels or forming passages from theslots the interior of the storm window. I

A further specific object of the present invenor openings to tion is toprovide an improved ventilatinga-ssem-;

blage which may be quickly and easily installed on existing storm sash,which may be manufactured and sold at moderate cost, and which isdurable in construction and attractive in appearance.

Still another specific object of the present invention is to provide animproved ventilating device of the type having an elongated adjustablecover plate adaptedto snugly engage the- These and other specificobjects and advantages of the present improvement will be apparent fromthe following detailed description.

A clear conception of the, invention, and of the mode of constructing,applying, and utilizing the improved had by referring to, the drawingaccompanying and forming a part of this specification, wherein likereference characters designate the same or.

similar parts in theseveral views.

Fig. 5 is a longitudinal horizontal section through the sash rail of themodified assemblage of Fig. 4, taken along the line 5-5.

While the invention has been shown and described herein as beingembodied in a storm sash ventilator wherein the lower sash rail isprovided with a series of circular holes adapted to be covered to variedextents by a sheet metal closure plate of a particular design, it is notmy desire or intent to thereby unnecessarily restrict or limit the scopeor utility of the improvement, since the ventilating appliance mayobviously be associated with other types of closures and may be formedof other materials.

Referring to the drawing, the improved ventilator is shown therein asapplied to a storm sash or window of usual construction having a lowerrail 8 provided with either a horizontal air admission slot or a seriesof air admission holes 9 formed therethrough and associated with atransparent window pane ID.

The improved ventilating assemblage shown particularly in Figs. 1 to 3comprises, in general, an elongated closure or cover plate II ofsufficient size to cover the slot or all of the air admission holes 9and being pivotally secured at an end thereof to the bottom rail 8 as atI2 with a hook shaped projection I3 at the opposite end adapted to coastwith a stop pin I4 or the like on the bottom rail 8 to definitely locatethe cover I I in closed horizontal position when swung counterclockwiseabout the pivot I2; and the cover plate II is dished and is formed witha stepped flange or ridge I5 about the marginal edge thereof to providerigidity and snug seating engagement with the inner surface of the rail8, the flange I5 i,

being provided along the upper sash engaging portion thereof with aseries of spaced, upwardly directed channels or grooves I6 formingpassages from the slot or each of the air admission holes 9 to theinterior of the sash and toward the pane I0 thereof.

The cover plate II may obviously be formed of sheet metal with the aidof punches and dies, or it may be formed of Wood, molded plastic orother non-metallic material as desired. This cover plate II may also bemade in various shapes, and may be readily provided with a socket H ofany desired shape and size adjacent the swinging end thereof to providea convenient finger-receiving means for facilitating manipulation of thecover I I about the pivot I2 in an obvious manner to open and closedposition. The plate I I may also be attractively decorated as byproviding any number of spaced ribs I8 on the face thereof, and whenthese ribs I8 are formed longitudinally of the plate i I, they aid instrengthening and reinforcing the shallow U-shaped plate member. Anyordinary screw or bolt may be used for the pivot I2 as well as the stopI4; and while any desired number of the channels or grooves I6 may beprovided in the upper portion of the marginal flange I5, it is desirable to space these channels a more or less uniform distance apart toobtain a more even distribution of 'air over the glass pane I0, and whena series of holes 9 are provided, as shown, instead of a singleelongated slot for air admission, it is preferable to provide a channelI6 for each of the holes 9.

The modified assemblage shown in Figs. 4 and 5 is substantially likethat hereinabove described with reference to Figs. 1 to 3 with theexception of the limit stop means for the closure or cover. Referring toFigs. 4 and 5, the ventilating assem blage shown therein comprises, ingeneral, an elongated cover member I I for the air admission slot orholes 9 pivotally secured at one end to the inner surface of the bottomrail 8 and having the free end I3 thereof inclined with respect to itstop and bottom edges so that the top edge is longer than the bottomedge, and a stop member I4 fixedly secured to the bottom rail 8' in anysuitable manner and having a similarly inclined flanged portion arrangedto engage and overlap the inclined free edge of the cover plate I I soas to arrest downward movement of the cover plate when the same islowered about its pivot in a counterclockwise direction. The cover plateII of the modified device is likewise dished to a shallow U-shape and isformed with a stepped flange I5 about the marginal edge thereof toprovide rigidity and snug engagement with the rail 8', and the flange I5is provided along the upper sash-engaging portion thereof with a similarseries of spaced-apart, upwardly directed channels or grooves I6 formingpassages from each of the holes 9' to the interior of the sash andtoward the pane thereof.

As shown, the stop member I4 may be positioned so as to partly overlapthe end hole 9' to save material, and the inclined flanged edge thereofmay be curved outwardly at the upper portion thereof to provide one ofthe channels I6. The parts of the modified assemblage may likewise beformed of metal, wood, plastic or the like, and may assume any desiredshapes. A finger-manipulating socket I'I' may also be preferably formedin the cover plate II, and the plate II as well as the stop member I4may be decorated with ribs I8 or the like which add rigidity thereto.The stop member I4 may be fixedly attached to the rail 8 in an obviousmanner by screws or the like, and a screw or bolt may form the pivot forthe plate II as shown with reference to Figs. 1 and 2.

In actual use of the improved device, the cover plate II, II is firstapplied to the sash rail 8, 8' by means of the pivot pin or screw I2 forsliding cooperation therewith about the pivot and the stop member I4, I4is then likewise secured to the sash rail in proper position so that theopenings 9, 9 are concealed when the cover is in its normal horizontalposition as shown by full lines in the drawing. The marginal flange I5,I5 of the U-shaped cover II, II is then maintained in snug engagementwith the inner surface of the rail 8, 8' except at the local upperportions where the channels or grooves I6, I6 are formed; and whetherthe cover plate is. in fully closed position or in partially openposition, these channels or grooves form passages at the upper edge ofthe cover to direct a limited amount of air in the form of jetsuniformly from the air admission holes 9, 9 upwardly toward and acrossthe inner surface of the pane ID, thereby tending to equalize thetemperature on the inner and outer surfaces of the pane to minimize thepossibility of condensation or frost formation and likewise tending toraise the humidity within the enclosure. The air seepage through thechannels I6, I6 is so directed and controlled in limited quantities thatthe effects thereof on the insulation value of the storm sash are notappreciable, but the benefits derived from elimination of condensationand frost formation are highly desirable. If it is desired to admit agreater amount of fresh air to the enclosure without opening the stormsash, the cover plate H, H may be conveniently and quickly raised in aclockwise direction about its pivot, as shown by means of dotand-dashlines in Fig. 1, upon insertion of one or more fingers in the socket I1,I'! and manipulation thereof in an obvious manner to any desiredposition.

From the foregoing detailed description, it will be apparent that mypresent invention contemplates provision of an improved storm sashventilating assemblage which is exceedingly simple, compact, and durablein construction, and which is moreover highly efficient and flexible inuse. The devices may be produced in a rapid manner from sheet metal,wood, plastic, or the like, and may be readily installed on existingstorm sash or on new sash at extremely low cost and with the aid ofstandard tools. The cover plate II, II as well as the stop member l4, l4may be attractively decorated with ribs I8, I 8' or the like which alsoserve to strengthen and add rigidity thereto, and these devices mayobviously be applied to and utilized with any standard storm sash havingeither a single elongated air vent slot or a series of spaced vent holes9, 9' as shown. Undesirable uncontrolled air drafts and seepage isminimized by the flange or shoulder 15, I which snugly engages the innersurface of the rail 8, 8' about the air admission holes, and undesirablecondensation and frost formation is minimized and proper humiditymaintenance is aided by reason of the spaced channels I6, 16'.

It should be understood that it is not desired or intended to limit thisinvention to the exact details of construction, or to the precise modeof use, herein shown and described, for various modifications within thescope of the appended claims may occur to persons skilled in the art towhich this invention pertains.
